Temp sensor

Kris · Post by **Kris** » Thu Nov 04, 2010 3:06 am

Hi,

I have an IP temperature sensor that returns a value from a SNMP request.
This is the temperature in degrees Celcius, with 1 decimal, like this: 24.3

I can see the value being returned to HM, but the History Charts are flat.

Why's that?

Thanks!
Kris

What symbol is used on your system as decimal separator? Comma? Then HostMonitor and Log Analyzer do not recognize 24.3 as a valid number

I´ve the same problem. I´ve changed the decimal separator in the control panel. But problem is in my case not solved. Can you tell me, what you have done?

Have you restarted HostMonitor after changing this option?

Ok, lets start from begining.
What test method do you use? SNMP Get? What value do you see in Reply field?
What software do you use to check performance charts? HostMonitor? Log Analyzer? Log Visualizer?
What version of the software do you use?

I use Hostmonitor 7.22. Test method is SNMP Get. Replyfield: between 7.1 and 12.0

BAD Value should be < 5 and > 30,
know i get
if reply is 9.9 - BAD on > 30
if reply is 10.0 - BAD on < 5

I´ve configured on regional options: decimal symbol as dot in numbers + currency, also turned on the option in advanced folder: "default user account settings - apply all settins to the current user account and default user profile" - reboot - same error.

Not sure I understand you.
1) SNMP GET test does not check minimum and maximim threshold at the same time. Unless you are using Optional status processing. Are you? So what exactly test settings do you use?

2) You said you have the same problem. So you have problem with history charts? Or you have problem with test status? That's a little different problem.

Regarding test status: SNMP protocol does not offer real/float numbers so usually SNMP agents send string (OPAQUE) counter when they need to provide real number. If you want to compare/check such strings as numbers, you should enable "Check OPAQUE data for float numbers" option for SNMP Credentials profile used for this test item.
Otherwise string data compared as strings, e.g. '2' > '10' , '9'>'1000', 'Abram'>'Mike'
